Aggregate Base Course (Type 3)

Aggregate Base Course in Type 3 Size Range

Aggregate Base Course in a Type 3 size range is a foundational construction material composed of crushed stone, gravel, or recycled concrete. This material is engineered to provide a stable, load-bearing layer beneath roads, driveways, parking lots, and building pads. The Type 3 size range typically includes a well-graded mix of larger and smaller particles, which enhances compaction and interlock for superior structural support.




The specific gradation of Type 3 aggregate base course ensures excellent load distribution and minimizes voids, making it ideal for high-traffic areas and heavy-duty applications. Its composition allows for efficient drainage while maintaining stability, reducing the risk of shifting or settling over time. Common uses include sub-base layers for highways, commercial developments, and residential driveways. The main advantage of this size range is its balance between compaction and drainage, though it may require mechanical compaction equipment for optimal performance.
